Domain and forest functional level currently operating at Windows server 2012 R2. In here, the FSMO role holder is running windows server 2012 R2.
In this demo I am going to demonstrate how to migrate from Active Directory 2012 R2 to Active Directory 2019. So, it is time me to write about AD 2019 migrations. In past I have written many articles about domain migrations by covering different Active Directory versions. Windows Server 2019 was available for public (GA) from early October 2018.
